Maximum production in hedgerow olive orchards is likely not achieved with maximum evapotranspiration over the long-term. Thus, regulated deficit irrigation (RDI) should be considered as a management option. Four irrigation treatments were evaluated during the summer when olive is most drought resistant. Control (CON) was irrigated to maintain the rootzone close to field capacity. Severe water deficit was applied by irrigating 30% CON from end of fruit drop to end July (DI-J) and from end July until beginning of oil synthesis (DI-A). Less severe water deficit was applied during July and August (DI-JA) by irrigating 50% CON. Flowering, fruiting, abscission, fruit development, fresh and dry weight of fruits, and oil production were evaluated. There were not significant differences in number of buds initiated, number of fruits per inflorescence and fruit drop. Oil production was significantly different between irrigation treatments in all experimental years. CON produced more oil and fruit with higher oil% than DI-A and DI-JA. Oil production of DI-J was not significantly reduced compared to CON and oil% was greater. DI-J was the most effective RDI strategy; with 16% less applied water relative to CON average loss in oil production of 8% was not significantly different to CON. While DI-JA saved most water (27%), oil production was reduced by 15%. Greatest loss in oil production (21%) was observed in DI-A with water saving of 22%.

“…irrigating, fertilizing, spraying and pruning. The literature describes the stage II of fruit growth in medium-and late-maturing cultivars, and the postharvest period as the most suitable for reducing irrigation in peach trees (Ruiz-Sánchez et al, 2010); however, deficit irrigation strategies should be adjusted to limit water deficits during the exceedingly long postharvest period for early-maturing peach cultivars .…”

“…The application of regulated deficit irrigation requires an accurate knowledge of the critical phenological periods during which the sensitivity of plants to water stress is maximal (Girona et al, 2005;Ruiz-Sánchez et al, 2010;Vera et al, 2013). However, the availability of carbohydrate resources also limits reproductive growth and, thus, it has been reported that carbohydrate distribution within the tree − fruit number and position (thinning), vegetative growth and tree configuration (pruning) − affect peach yield (DeJong, 1999;Naor et al, 1999;López et al, 2006).…”

The objectives of the paper were to study the pattern of root growth (measured by minirhizotrons) in relation to trunk, fruit and shoot growth and the effects of crop load on tree growth and yield in peach trees. Two crop load (commercial and low) treatments were applied in a mature early-maturing peach tree orchard growing in Mediterranean conditions. Root growth dynamics were measured using minirhizotrons during one growing season. Shoot, trunk and fruit growth were also measured. At harvest, all fruits were weighed, counted and sized. Roots grew throughout the year but at lower rates during the active fruit growth phase. Root growth was asynchronous with shoot growth, while root and trunk growth rates were highest after harvest, when the canopy was big enough to allocate the photo-assimilates to organs that would ensure the following season's yield. Shoot and fruit growth was greater in the low crop load treatment and was accompanied by a non-significant increase in root growth. High level of fruit thinning decreased the current yield but the fruits were more marketable because of their greater size.Additional keywords: fruit growth; minirhizotrons; phenology; Prunus persica L.

“…Though, the response of trees to water stress may have distinct consequences according to the moment of application, the intensity of stress and its duration (Ruiz-Sánchez et al, 2010) and the use of the traditional methodologies led to high variability and uncertainties to provide an accurate water supply in time and quantities since tree water use results being a complex process integrating the effect of all these factors.…”

(2016 RESUMENEl objetivo general de esta tesis doctoral fue optimizar la gestión del riego en el pistachero en base a la aplicación de estrategias de riego deficitario controlado (RDC) y el uso de indicadores del estado hídrico de la planta. Este propósito implicaba la evaluación de la aplicabilidad y utilidad del potencial hídrico del tronco (Ψ s ) como herramienta para la programación del riego, así como la evaluación de las respuestas agronómicas y fisiológicas del pistacho a diferentes regímenes de riego y porta-injertos.Para este propósito, pistacheros del cultivar "Kerman", injertados sobre tres patrones diferentes (Pistacia Terebinthus, Pistacia atlantica y Pistacia integerrima) fueron sometidos a tres regímenes de riego. Una estrategia de riego optimo satisfaciendo el 100 % de las necesidades hídricas de los árboles, ajustando estas dotaciones con medidas de potencial hídrico del tronco, y dos estrategias de riego deficitario controlado.El éxito de una estrategia de RDC depende de la precisión del manejo del estrés hídrico siendo el tiempo, la duración y la severidad del estrés aplicado sus principales componentes. Por lo tanto, la aplicación de las estrategias de estrés hídrico se llevó a cabo intentando definir con precisión las fases de crecimiento del fruto y basándose en un umbral establecido del potencial hídrico del tronco.Los tratamientos de RDC se regaron como el control durante toda la temporada, excepto durante la fase II de crecimiento del fruto en el que un nivel de estrés hídrico de -1.5 MPa se impuso a la primera estrategia (T1) y -2.0 MPa a la segunda (T2). El estudio se llevó a cabo durante tres años (2012, 2013 y 2014), en una parcela de pistacho situada en Ciudad Real (Castilla-La Mancha, España).Este trabajo se ha dividido en dos partes principales; la primera parte trata con la respuesta ii fisiológica del pistacho estudiando sus relaciones hídricas y ajustando la programación del riego a las necesidades del cultivo. En la segunda parte se propuso estudiar su respuesta agronómica comparando el crecimiento vegetativo y el potencial productivo en función de cada tratamiento y porta-injerto.El resultado principal de este estudio fue la posibilidad de programar con precisión el riego en una plantación de pistachos cultivados en suelos poco profundos a base de medidas del potencial hídrico del tronco. La utilización del potencial hídrico para la programación de riego se ha traducido en una ec...
